What does the Bible say about righteousness with God?

In Isaiah 26:2, it is proclaimed that there is a 'righteous nation' which keeps the truth, indicating God’s elect are made righteous in His sight. This righteousness is not earned but is an imputed gift from God, highlighting the doctrine of justification by faith. Paul emphasizes in Romans 3:22-24 that righteousness comes through faith in Jesus Christ for all who believe, underpinning that it derives from grace alone, not from our works. This understanding is integral to the Gospel message, affirming that we are justified freely by His grace through the redemption that is in Christ Jesus.
